If you've been told you need a dental crown, you might wonder why a filling is not sufficient. The truth is, a dental filling is designed to repair a small area of tooth structure that's been damaged by decay, while a crown restores your whole tooth.
Crowns cover the entire structure of your remaining tooth down to the gumline, protecting the integrity of your root. Here are some of the circumstances where your Aston dentist may recommend a tooth crown.
#1: To Replace a Large Filling
If you've lived with large metal fillings in your teeth, you may begin to notice a grey hue surrounding your restoration. Metal fillings can break down over time and begin to pull away from your tooth, letting bacteria in. That bacteria can start to cause decay in your tooth again, which is why your tooth may look dark or grey.
If you have large fillings that have broken down over time, your dentist may recommend a tooth crown to repair your teeth. A crown will cover your teeth and keep bacteria from reentering. Better yet, a porcelain crown will eliminate the darkness in your tooth and provide you with the appealing aesthetics you want for your smile.
#2: To Repair a Cracked or Fractured Tooth
A broken tooth can cause pain and discomfort, not to mention diminish the appearance of your smile. A dental crown is an ideal restoration to restore your tooth and enhance your smile.
#3: To Rebuild a Tooth That's Had Root Canal Treatment
When you suffer from a tooth infection, your dentist has to access the inside of your tooth and remove the infected tissue to preserve it. This process is called root canal treatment, and afterward, your tooth is more brittle than before.
A crown covers your tooth and strengthens it after root canal treatment so you can eat and chew with ease again.
#4: To Restore a Dental Implant
When you lose a tooth, it's important to think about replacing it. A dental implant restores both your root with the implant itself and your tooth with a porcelain crown.
